Synthesis

a + b = ab , no cation+anion compounds

Combustion

Always has CH and O in the reactants → always becomes CO₂ and H₂O

Single Replacement/Displacement

a + bc = b + ac, a must be higher than b on an activity series

Double Replacement/Displacement

ab + cd = ad + bc, a/c = +, b/d = -

Not Reactive

when the cations don’t pass the one it’s replacing on the activity series
